I went from a 650 down to a 600. The primaries in the 650 are bigger then the secondaries in the 600 The Holley 650 primaries and secondaries were the same size. The edelbrock has smaller primaries and larger secondaries. Its also better on gas.

OK I have been real lazy and not updated this.
I have to motor cleaned up and installed in my GT.
The wiring is done I just need to install some loom to clean it up.
I haven't driven it yet because I still have to fix the clutch.
Its been fun working on it but frustrating at the same time.

Well my wife being the fine person she is helped out on that end. I attribute all the problems Jason had with the car to the car he started with. It was just past its prime.
On our 16th wedding anaversery my wife bought me a 1986 Pontiac GT. It has a 5 speed and is in real nice shape.
